Petrified Dragon Bone


A large petrified bone. Reinforces equipment made from special souls.
Commonly called dragon bone, but the veracity of the name is questionable. In any case, this petrified bone houses great power.

Petrified Dragon Bone is a type of upgrade material in Dark Souls 2.


Farming without using a Bonfire Ascetic


  • Used to upgrade boss soul weapons.
  • 15 needed to max out just ONE weapon. A significant amount.



  • 1 on a corpse in the Iron Keep after turning off the fire in the room near the Smelter Demon.
  • 1 on a corpse on the broken staircase naer the Pharros contraption before the Smelter Demon room.
  • 1 on a corpse hanging from the broken staircase opposite to the Smelter Demon boss room.
  • 1 in the Shaded Woods, in a wood chest one level above the "Shaded Ruins" bonfire (can be respawned by burning a Bonfire Ascetic).
  • 1 in the Doors of Pharros, inside a trapped chest near the spike walls.
  • 1 on a corpse in Brightstone Cove Tseldora, out the door and right from the "Lower Brightstone Cove" bonfire.
  • 1 from the blue crystal lizard in Brightstone Cove Tseldora near the "Chapel Threshold" bonfire.
  • 1 on a corpse in Lost Bastille, in the room next to the Straid's Cell bonfire room (requires the Bastille Key to open the room).
  • 1 in a chest in one of the side rooms with the two Warrior Giants below Black Gulch.
  • 1 on the corpse before the Looking Glass Knight boss room, in the passage way with Stone Knights.
  • 1 in the Shrine of Amana, after the third bonfire lying in the water.
  • 1 in the Undead Crypt, in the first room past the second bonfire on the ground.
  • 1 on the ground, in a bush just after and left of the gate before Aldia's Keep, near the first bonfire. Right where you get attacked by the rat-dog things who try to petrify you.
  • 1 after the skeleton dragon in Aldia's Keep in the mirror gallery behind the stairway.
  • 1 in the pool of corrosive acid past the second bonfire Aldia's Keep. (Farm this one as you farm Dragon Scale and Soul Geyser).
  • 2 can be found on corpses in the Dragon Aerie. The treasure is behind the dragon eggs on the path to the right before the second wyvern (it is also worth noting that it is possible to farm the crystal lizards in the area for the bones as they frequently drop them, however, this requires the use of bonfire ascetics).
  • 3 in Dragon's Sanctum in the hallway with the repeating arrow trap after hitting the switch on the ceiling.
  • 8 can be found in an iron chest in Brume Tower behind a breakable wall in the room past the Foyer Bonfire by blowing up a barrel kobold near it.
  • 2 can be found on a corpse in the tower where you retrieve the Scorching Iron Scepter.
  • 3 can be purchased from Stone trader Chloanne for 17500 each (after obtaining the King's Ring).
  • Possible trade for Petrified Something, Smooth & Silky Stone, or Small Smooth & Silky Stone from Dyna and Tillo at Things Betwixt;

Farming with Bonfire Ascetics:

  • 3 Petrified Dragon Bone in addition to 3 Twinkling Titanite can be farmed indefinitely in Dragon's Sanctum by using a bonfire ascetic on the Tower of Prayer bonfire then making your way to the wooden chest after the spike trap room while making sure to pick up the bonfire ascetic in another wooden chest along the way. This method requires only a single bonfire ascetic to start and will replenish itself each run. The enemies on this run are very susceptible to Yearn / Alluring Skulls, which can make the trip much more efficient on higher bonfire intensities. The Bonfire Ascetic doesn't respawn in Scholar of the First Sin).
  • Alternatively, the Lair of the Imperfect bonfire in Dragon's Sanctum, although not infinite, this route provides 3 Petrified Dragon Bones, Human Effigy, Dried Root, a duplicate of Drakeblood Greatsword and more drops from The Imperfect.
  • Also, you can try farming the lizards at Dragon Aerie (and a corpse outside near the 2nd dragon has 2 bones every time). The Dragons have a chance to drop Bones.

        Aldia's Keep seems good for this, from the second bonfire near the acid pool. There is a mimic in the room with the warlock / gargoyle / hammer bros that drops a bonfire ascetic, the hammer bros have a chance of dropping a petrified dragon bone, and the caged area with the acid has a respawning body with a dragon bone. Pretty good farming spot. You're guaranteed at least 1 per ascetic, and will likely get 5+ (and a lot of souls) if you farm the acolytes + gargoyle + warlock until they're all dead. I take down the warlock and gargoyle with poison arrows and just greatsword spam the acolytes.

            Ascetic farming method on tower of prayer bonfire is relevant only in vanilla version of the game. I believe in sotfs it was fixed by replacing wooden chests with metal ones

              Jesus. I take my comment back. Hes just not explaining it right. The spike trap room he mentioned is the one where the spikes come through the walls on the stairs, there are 2 wooden chests that do respawn.

                  The easiest way to farm these Petrified Dragon Bones is, i believe, is in Dragon Aerie. Yes, you have to burn Bonfire Ascetic every time, but in the first "cave" you go into, there is everytime new Bonfire Ascetic on the first corpse. In first Wyvern nest, on the right side is the first one (dropped from Crystal Lyzard). Two more bones on right side before you enter second Wyvern nest on corpse and one more is dropped from one Crystal Lyzard in the second Wyvern nest. So its 4 Petrified Dragon Bones almost for free.

                    The Best Farming Location (VERY high drop-rate)29 Aug 2016 10:57  

                    Farming the Imperfect (Dinosaur monsters) by the third bonfire is by far the easiest way. They have an insanely high drop rate with serpent ring +1 and Symbol of Avarice. Additionally, they also drop Titanite slabs and Dragon Scales!
